Definitions

  • the present invention regards a universal traversing assembly for legs of cranes, or the like or mobile structures of other kinds.
  • Conventional traversing assemblies comprise one or more platforms which are fitted at the bottom of the legs of the crane or mobile structure and have a plurality of supporting wheels, some of which are driving wheels and some of which are driven wheels; said wheels are actuated by electric motors, or motors of another type, with conventional transmission systems interposed and are made to roll on rails fixed to the ground.
  • the gauge of the track i.e. the distance between the two rails on which the pairs of mutually opposite legs rest, is often too small with respect to the dimensions of the crane, the balance of which is therefore precarious and unsteady.
  • the aim of the present invention is to eliminate the above noted drawbacks of conventional types of traversing assembly by providing a universal traversing assembly for legs of cranes or the like which allows each leg to perform a complete and independent traversing motion, to exactly size the gauge between the rails so as to always have structures stable and balanced without having to ballast them, to use the crane on any terrain, to render the traversing motion of the crane independent of long, fixed and existing rails and to modify the position and length of the rails according to the different operating conditions, without requiring work for modification, assembly and disassembly thereof.
  • An object of the present invention is to allow to place and use the crane in sites different from the initial ones, if this need arises due to war or other events, by rendering the traversing motion of the crane independent of the rails.
  • another object of the present invention is to achieve the above aim and object with a structure which is simple, relatively easy to provide in practice, safe in use, effective in operation, and relatively low in cost.
  • the present universal traversing assembly for legs of cranes or the like, comprising a platform provided with a plurality of driving wheels and supporting wheels which are aligned and are adapted to roll on a long underlying rail for the traversing motion of the leg, characterized in that it comprises: a box-like tunnel which rests on the ground, is open in an upward region, and has a portion of the rail fixed to its base; at least one pair of idler wheels, which are freely mounted on the platform, are mutually coaxial and are arranged below a pair of upper guides fixed on the tunnel at the upper opening; a rack which is fixed to the side of the rail portion and is adapted to mesh with pinions which are rigidly coupled and coaxial with respect to the driving wheels; at least one motorization assembly which is rigidly coupled to the platform and is coupled to at least one of said driving wheels and pinions; at least one stabilizer comprising at least one ground resting foot which has an adequate surface, can slide vertically and is adapted to move from a lowered configuration for supporting the
  • 1 generally designates a crane in which each one of the legs 2 is provided with a universal traversing assembly 3 according to the invention.
  • the assembly 3 comprises a box-like tunnel 4 which has an adequate ground resting surface so as to reduce its pressure, is open in an upward region and has a portion of a rail 5 fixed to its base for the traversing motion of the leg 2.
  • a platform 6 is provided with two driving wheels 7 and with an idler supporting wheel 8 which are mutually aligned and are adapted to roll on the portion of rail 5.
  • Two pairs of mutually coaxial idler wheels 9 are freely mounted on the platform 6 and are arranged below a pair of upper guides 10 which are fixed to the tunnel 4 at the upper opening 11.
  • a rack 12 is fixed to the side of the portion of rail 5 and is meshed by respective pinions 13 which are rigidly coupled and coaxial to the two driving wheels 7.
  • the assembly 3 further comprises two motorization assemblies 14 which are rigidly coupled to the platform 6 and are coupled to elements for transmitting motion 15 to the respective driving wheels 7 and pinions 13.
  • Two stabilizers 16 are fixed to the leg 2 externally and laterally to the tunnel 4, and each one comprises two feet 17 for resting on the ground which can slide vertically in order to move from a lowered configuration for supporting the leg 2 to a raised inactive configuration.
  • the tunnel 4 In the supporting configuration, the tunnel 4 is raised from the ground and the pinions 13 produce the traversing motion of the tunnel 4 with respect to the leg 2; in the inactive configuration, the tunnel 4 rests on the ground, which can be of any kind, and the driving wheels 7 produce the traversing motion of the leg 2 with respect to the tunnel 4.
  • the rail portion 5, the rack 12 and the pair of guides 10 are mutually parallel and run along the entire length of the tunnel 4.
  • the transmission elements 15 are constituted by two sprockets 18 on which a chain 19 closed in a loop is wound, but it is possible to provide alternative embodiments of said elements.
  • the driving wheels 7 are mutually independent and have a motorization assembly 14 of their own which is constituted by a motor 20 of the electric, hydraulic or other type and by a reduction unit 21.
  • the platform 6 supports one of the driving wheels 7 and a secondary platform 22 for supporting the second driving wheel 7 and the idler wheel 8.
  • the pairs of idler wheels 9 are mutually aligned and are arranged between the two driving wheels 7 and the supporting wheel 8, above them.
  • said tunnel is provided, at its two ends, with sliding rollers 23 provided with lifting means 24 of the hydraulic or other type which can be actuated in the raised inactive configuration of the feet 17: said rollers 23 prevent the tunnel 4 from sliding on the ground.
  • the crane 1 can perform a traversing motion in both directions of travel by means of the wheels 7 and 8 of each leg 2, which can slide on the rail portions 5 inside the respective tunnels 4, having a length related to the dimensions of the machine, depending on the space occupation and the tasks that said machine must perform.
  • Each tunnel 4 performs a traversing motion by means of the pinions 13 and the rack 12, which are actuated by the same motorization assemblies 14 and transmission elements 15 used for the traversing motion of the leg 2 of the crane 1.
  • the described invention achieves the intended aim and objects, i.e. to allow to use the crane on any terrain, becoming independent of the loads allowed on the runways, to rest the crane directly on the ground, allowing to widen or narrow, according to requirements or to the space available, the ground resting bases of the traversing assembly, so as to adapt to the load-bearing capacity of the ground and therefore be able to adapt to the existing ground without requiring structural work and also to allow the use of old wharves with limited capacities without having to perform modification or reinforcement work.
  • the present invention allows to provide each crane, regardless of its constructive dimensions, with an adapted track of its own, whose gauge and supporting surface have been adapted and sized according to that particular type of crane that it must support, so as to ensure its stability and balance on the various terrains on which it will be located.
  • the tunnels with which the invention is provided have a length which is a multiple of the length of containers, thus allowing the machine to perform movements equal to the length of the containers to be handled.
